Compact Mechanical Thermostat Controller (0–60°C) — KTO011 / KTS011 Key benefits Accurate temperature control inside enclosures using a reliable thermostatic bimetal sensor and snapaction mechanism to reduce temperature drift and protect sensitive components. Prevents rapid cycling and component stress with a builtin hysteresis of 7K ± 4K, extending the life of heaters and fans. Quick to install and adjust: DIN35 rail compatible and fitted with a clear, adjustable knob for fast setpoint changes without tools. Durable construction tested for long service life: over 100,000 switching cycles and robust electrical connection ratings. What it does and why you need it Regulates temperatures between 0°C and 60°C for heating and cooling systems inside electrical enclosures. Two model functions: KTO011 (normally closed) for controlling heaters; KTS011 (normally open) for controlling cooling fans. Selecting the correct model helps prevent overheating or overcooling of components. The snapaction mechanism and thermostatic bimetal sensor give repeatable switching at the chosen setpoint, keeping cabinet temperatures within safe limits. Key features and specifications Temperature range: 0–60°C, adjustable via a clearly marked knob. Hysteresis: 7K ± 4K for stable switching and reduced relay/fan/element wear. Mounting: Compatible with DIN35 rail for quick, secure installation in electrical cabinets. Actuation options: Red or blue button options available. Mechanical details: Snapaction (mechanical) thermostat with thermostatic bimetal sensor. Durability: Tested for >100,000 cycles. Electrical connection: Accepts up to 2.5 mm² wire; recommended max clamping torque 0.5 Nm. Housing: IP20 lightgrey plastic, rated for use in environments up to 80°C and 90% RH (non‑condensing). Typical applications Electric cabinets and control panels: Maintain safe internal temperatures for PLCs, power supplies, and control electronics. Fan filter units and cooling systems: Control fans to remove heat when cabinet temperature rises (use KTS011 normally open). Heater control for anticondensation and freeze protection inside enclosures: Activate heating elements only when needed (use KTO011 normally closed). Practical benefits for installers and operators Easy setpoint adjustment with a visible scale reduces setup time and errors during commissioning. DIN35 rail compatibility speeds installation and replacement in standard control cabinets. Robust mechanical design and long cycle life lower maintenance frequency and reduce downtime. Clear model selection (KTO011 for heaters, KTS011 for fans) simplifies system design and prevents incorrect wiring. Ordering tip Choose KTO011 when you need a normally closed thermostat for heating control; choose KTS011 when you need a normally open thermostat for cooling/fan control. Specifications summary Model: KTO011 (NC) / KTS011 (NO) Range: 0–60°C (adjustable) Hysteresis: 7K ± 4K Mounting: DIN35 rail compatible Wiring: up to 2.5 mm², max clamping torque 0.5 Nm Housing: IP20, light grey plastic; up to 80°C, 90% RH non‑condensing Mechanical life: >100,000 cycles This compact mechanical thermostat provides reliable, serviceable temperature control for enclosure heating and cooling applications while minimizing wear on switching devices.
